| 1 | Effects of arbuscular mycorrhizal fungi inoculation on arsenic accumulation by tobacco (Nicotiana tabacum L.)显示文摘A pot experiment was conducted to study the effects of arbuscular mycorrhizal(AM) fungi(from contaminated or uncontaminated soils) on arsenic(As) uptake of tobacco(Nicotiana tabacum L.) in As-contaminated soil.Mycorrhizal colonization rate,dry weight,As and P uptake by plants,concentrations of water-extractable As and As fractions were determined.A low mycorrhizal colonization rate(<25%) was detected.Our research indicated that AM fungi isolated from polluted soils were no more effective than those from unpolluted soils when grown in symbiosis with tobacco.No significant differences were observed in roots and stalks dry weights among all treatments.Leaves and total plant dry weights were much higher in Glomus versiforme treatment than that in control treatment.As contents in roots and stalks from mycorrhizal treatments were much lower than that from control treatment.Total plant As content exhibited the same trend.P concentrations in tobacco were not affected by colonization,nor were stalks,leaves and total plant P contents.Roots P contents were remarkably lower in HN treatments than in other treatments.Meanwhile,decreased soil pH and lower water-extractable As concentrations and higher levels of As fraction bound to well-crystallized hydrous oxides of Fe and Al were found in mycorrhizal treatments than in controls.The protective effect of mycorrhiza against plant As uptake may be associated with changes in As solubility mediated by changing soil pH.These results indicated that under As stress,proper mechanisms employed by AM fungi can protect tobacco against As uptake.Results confirmed that AM fungi can play an important role in food quality and safety. | HUA Jianfeng LIN Xiangui YIN Rui JIANG Qian SHAO Yufang | 2009 | Journal of Environmental Sciences2009，21，9： | 19 |
| 2 | Effect of organic wastes on the plant-microbe remediation for removal of aged PAHs in soils显示文摘The effectiveness of in-situ bioremediation of polycyclic aromatic hydrocarbons(PAHs) may be inhibited by low nutrients and organic carbon.To evaluate the effect of organic wastes on the PAHs removal efficiency of a plant-microbe remediation system,contaminated agricultural soils were amended with different dosages of sewage sludge(SS) and cattle manure(CM) in the presence of alfalfa(Medicago sativa L.) and PAHs-degraders(Bacillus sp.and Flavobacterium sp.).The results indicated that the alfalfa mean biomasses varied from 0.56 to 2.23 g/pot in root dry weight and from 1.80 to 4.88 g/pot in shoot dry weight.Low dose amendments,with rates of SS at 0.1% and CM at 1%,had prominent effects on plant growth and soil PAHs degradation.After 60-day incubation,compared with about 5.6% in the control,25.8% PAHs removal was observed for treatments in the presence of alfalfa and PAHs-degraders;furthermore,when amended with different dosages of SS and CM,the removed PAHs from soils increased by 35.5%-44.9% and 25.5%-42.3%,respectively.In particular,the degradation of high-molecular-weight PAHs was up to 42.4%.Dehydrogenase activities(DH) ranged between 0.41 and 1.83 μg triphenylformazan/(g dry soil·hr) and the numbers of PAHs-degrading microbes(PDM) ranged from 1.14×10 6 to 16.6×10 6 most-probable-number/g dry soil.Further investigation of the underlying microbial mechanism revealed that both DH and PDM were stimulated by the addition of organic wastes and significantly correlated with the removal ratio of PAHs.In conclusion,the effect of organic waste application on soil PAHs removal to a great extent is dependent on the interactional effect of nutrients and dissolved organic matter in organic waste and soil microorganisms. | Jing Zhang Xiangui Lin Weiwei Liu Yiming Wang Jun Zeng Hong Chen | 2012 | Journal of Environmental Sciences2012，24，8： | 11 |
| 3 | Tolerance of VA Mycorrhizal Fungi to Soil Acidity显示文摘A 45-day greenhouse experiment was carried out to determine effect of vesicular-arbuscular (VA) mycorrhizal fungi on colonization rate, plant height, plant growth, hyphae length, total Al in the plants, exchangeable Al in the soil and soil pH by comparison at soil pH 3.5, 4.5 and 6.0. Plant mung bean (Phaseolus radiatus L.) and crotalaria (Crotalaria mucronata Desv.) were grown with and without VA mycorrhizal fungi in pots with red soil. Ten VA mycorrhizal fungi strains were tested, including Glomus epigaeum (No. 90001), Glomus caledonium (No. 90036), Glomus mosseae (No. 90107), Acaulospora spp. (No. 34), Scutellospora heterogama (No. 36), Scutellospora calospora (No. 37), Glomus manihotis (No. 38), Gigaspora spp. (No. 47), Glomus manihotis (No. 49), and Acaulospora spp. (No. 53). Being the most tolerant to acidity, strain 34 and strain 38 showed quicker and higher-rated colonization without lagging, three to four times more in number of nodules, two to four times more in plant dry weight, 30% to 60% more in hyphae length, lower soil exchangeable Al, and higher soil pH than without VA mycorrhizal fungi (CK). Other strains also could improve plant growth and enhance plant tolerance to acidity, but their effects were not marked. This indicated that VA mycorrhizal fungi differed in the tolerance to soil acidity and so did their inoculation effects. In the experiment, acidic soil could be remedied by inoculation of promising VA mycorrhizal fungi tolerant of acidity. | LIN XIANGUI, WANG SHUGUANG and SHI YAQIN Institute of Soil Science, the Chinese Academy of Soil Sciences, Nanjing 210008 (China) | 2001 | Pedosphere2001，11，2： | 10 |
| 4 | Effect of Rhizobacterium Rhodopseudomonas palustris Inoculation on Stevia rebaudiana Plant Growth and Soil Microbial Community显示文摘There is an increasing concern that the continuous use of chemical fertilizers might lead to harmful effects on soil ecosystem.Accordingly, a biocompatible approach involving inoculation of beneficial microorganisms is presented to promote plant growth and simultaneously minimize the negative effect of chemical fertilizers. In this study, Rhodopseudomonas palustris, a plant growth-promoting rhizobacterium(PGPR), was inoculated into both fertilized and unfertilized soils to assess its influence on Stevia rebaudiana plant growth and microbial community in rhizosphere soils in a 122-d field experiment. Soil enzyme assays(dehydrogenase, urease, invertase, and phosphomonoesterase), real-time quantitative polymerase chain reaction(RT-_qPCR), and a high-throughput sequencing technique were employed to determine the microbial activity and characterize the bacterial community. Results showed that the R.palustris inoculation did not significantly influence Stevia yields and root biomass in either the fertilized or unfertilized soil. Chemical fertilization had strong negative effects on soil bacterial community properties, especially on dehydrogenase and urease activities.However, R. palustris inoculation counteracted the effect of chemical fertilizer on dehydrogenase and urease activities, and increased the abundances of some bacterial lineages(including Bacteroidia, Nitrospirae, Planctomycetacia, Myxococcales, and Legionellales). In contrast, inoculation into the unfertilized soil did not significantly change the soil enzyme activities or the soil bacterial community structure. For both the fertilized and unfertilized soils, R. palustris inoculation decreased the relative abundances of some bacterial lineages possessing photosynthetic ability, such as Cyanobacteria, Rhodobacter, Sphingomonadales, and Burkholderiales. Taken together, our observations stress the potential utilization of R. palustris as PGPR in agriculture, which might further ameliorate the soil microbial properties in the long run. | XU Jiangbing FENG Youzhi WANG Yanling LIN Xiangui | 2018 | Pedosphere2018，28，5： | 5 |
| 5 | Chronosequencing methanogenic archaea in ancient Longji rice Terraces in China显示文摘Chronosequences of ancient rice terraces serve as an invaluable archive for reconstructions of historical human-environment interactions. Presently, however, these reconstructions are based on traditional soil physico-chemical properties. The microorganisms in palaeosols have been unexplored. We hypothesized that microbial information can be used as an additional proxy to complement and consolidate archaeological interpretations. To test this hypothesis, the palaeoenvironmental methanogenic archaeal DNA in Longji Terraces, one of the famous ancient terraces in China, dating back to the late Yuan Dynasty(CE1361–1406), was chronosequenced by high-throughput sequencing. It was found that the methanogenic archaeal abundance, diversity and community composition were closely associated with the 630 years of rice cultivation and in line with changes in multi-proxy data. Particularly, the centennial-and decadalscale influences of known historical events, including social turbulences(The Taiping Rebellion, CE1850–1865), palaeoclimate changes(the Little Ice Age) and recorded natural disasters(earthquakes and inundation), on ancient agricultural society were clearly echoed in the microbial archives as variations in alpha and beta diversity. This striking correlation suggests that the microorganisms archived in palaeosols can be quantitatively and qualitatively analyzed to provide an additional proxy, and palaeo-microbial information could be routinely incorporated in the toolkit for archaeological interpretation. | Youzhi Feng Jan Dolfing Zhiying Guo Jianwei Zhang Ganlin Zhang Shijie Li Xiangui Lin | 2017 | Science Bulletin2017，62，12： | 4 |

| 18 | The roles and performance of arbuscular mycorrhizal fungi in intercropping systems显示文摘Intercropping,which gains productivity and ecological benefits through plant facilitative interactions,is a practice often associated with sustainable agriculture.In such systems,arbuscular mycorrhizal(AM)fungi and the hyphal networks play key roles in plant facilitation by promoting connectivity,mediating interplant transfer of metabolic resources,and managing weeds,pathogens,and contaminants.This review states that the symmetrically or unsymmetrically delivered resources via AM fungi are imperative to maintain facilitative interactions between intercrops.In addition,the responses of AM fungi to intercropping are also discussed,including changes in abundance,diversity,community composition and colonization level.Although general proliferations in AM fungi via intercropping have been shown,the plant hosts and neighbors may exert different influences on AM fungi.Therefore,further research is needed in quantifying the mediating role of AM fungi on outputs of intercropping systems,clarifying the driving forces,and exploring the causation between these processes and the changes in AM fungi themselves.To conclude,the integration with AM fungi extends the understanding of key soil biological processes driving plant facilitation and will guide efforts to optimizing intercropping systems. | Minghui Li Junli Hu Xiangui Lin | 2022 | Soil Ecology Letters2022，4，4： | 1 |
